Incidents & Scenarios #2026
Review multi-hazard incident logs and evaluate outcomes across Static Signage, Shortest-Route, and EVORA Adaptive guidance.
Scenario Library & Multi-Method Evaluation Matrix
Compares Static Signage, Shortest-Route Method, and EVORA Adaptive Recommendation across evacuation time, hazard exposure, route safety, worker density, and guidance update latency.
Scenario 1: Pressurized Hydrocarbon Gas Leakage
Simulates a flange gasket rupture on the Central Pipe Manifold (44.2% to 58.0% LEL vapor cloud) driven south-east and westward by shifting coastal winds.
Scenario 2: Storage Tank T-102 Bund & Rim-Seal Fire
Simulates ignition at Storage Tank T-102 south bund wall with high radiant heat flux (>85 deg C) and thermal impingement toward the central manifold.
Scenario 3: Rapid Downwind Smoke Propagation
Simulates dense particulate smoke (260+ ppm) sweeping across the East Pipe Corridor and Gantry Bay B under 6.4 m/s wind gusts, degrading visibility and accessibility.
Five-Dimension Evaluation Matrix · Scenario 1: Pressurized Hydrocarbon Gas Leakage
| Method | Evac Time | Exposure Idx | Route Safety | Peak Density | Latency |
|---|---|---|---|---|---|
Static Signage Illustrative demo value: fixed exit signs continue directing workers into the North-West vapor plume, forcing mid-corridor backtracking. | 268 s | 64 / 100 | 38 / 100 | 3.8 p/m2 | N/A (Static) |
Shortest-Route Method Illustrative demo value: distance-only routing favors the 245 m corridor without excluding zones exceeding the LEL risk threshold. | 242 s | 72 / 100 | 31 / 100 | 4.1 p/m2 | 420 ms |
EVORA Adaptive Recommendation Illustrative demo value: excludes corridors above risk threshold 65 and redirects Gantry groups via South Perimeter Bypass (Route B). | 195 s | 14 / 100 | 89 / 100 | 2.1 p/m2 | 280 ms |
Method Comparison Across Time, Exposure & Safety
Lower Evacuation Time and Exposure Index are safer; higher Route Safety Score is safer.

Pressurized Hydrocarbon Gas Leakage
Central Pipe Manifold & North-West Approach · 2026-11-10 09:48
Simulated flange leak on Central Pipe Manifold followed by secondary westward vapor expansion across Route A, triggering dynamic rerouting to Route B (South Perimeter Bypass).
Event & Decision Sequence
- IoT Telemetry09:47:10 WIB
Catalytic sensor GS-204 detects 44.2% LEL hydrocarbon vapor near Tank T-102 manifold.
- Digital Twin09:47:14 WIB
3D/2D spatial twin maps 78 m vapor plume vector at 135 deg SE (4.8 m/s wind).
- Routing Engine09:47:18 WIB
Route C (Central Manifold East) marked BLOCKED (Risk Score 76 > Threshold 65); Route A selected.
- Multi-Agent Sim09:48:30 WIB
Secondary pressure relief release expands plume westward over North-West Service Road.
- Routing Engine09:48:31 WIB
Route A risk rises to 74/100 (BLOCKED). EVORA promotes Route B (South Perimeter Bypass, Score 31/100) in 280 ms.
